Abstract

La présente invention concerne un système hydraulique destiné à une boîte de vitesses automatique, notamment à une boîte de vitesses à double embrayage, d'une véhicule à moteur, comprenant : un circuit haute pression (H) dans lequel sont reliés un accumulateur hydraulique (25), au moins un embrayage (K1, K2) et des actionneurs (22); et un circuit basse pression (N) destiné à refroidir l'embrayage (K1, K2), le circuit haute pression (H) et le circuit basse pression (N) présentant respectivement une pompe hydraulique de refroidissement (59) et une pompe hydraulique de chargement (53) qui peuvent être entraînées par un moteur électrique (57) commun; et un dispositif de commande (39) qui, lorsqu'une nécessité de chargement d'accumulateur hydraulique est identifiée, commande le moteur électrique (57) pour qu'il adopte une vitesse de rotation théorique de chargement (nthéorique, chargement) et/ou, lorsqu'une nécessité de refroidissement ou autre est identifiée, commande le moteur électrique (57) pour qu'il adopte une vitesse de rotation de refroidissement ou autre (nthéorique, refroidissement). Selon l'invention, le dispositif de commande (39), en l'absence de toute nécessité aussi bien de chargement d'accumulateur hydraulique que de refroidissement ou autre, abaisse la vitesse de rotation théorique (nthéorique) à zéro pendant un intervalle de temps prédéterminé (Δtarrêt). Après écoulement de l'intervalle de temps (Δtarrêt), le dispositif de commande (39) commande le moteur électrique (57) pour qu'il adopte au moins la vitesse de rotation de vérification (nvérif).
